CROSS REFERENCE TO RELATED APPLICATIONS

This application claims the benefit, under 35 USC 119(e), to U.S.Provisional Patent Application No. 61/990,335 filed on May 8, 2014,which is herein incorporated by reference in its entirety.

FIELD OF THE INVENTION

The present disclosure is directed to disposable absorbent articles andarrays of disposable absorbent articles which are designed to fitdifferent adult body sizes, shapes and types, and as such are sized tofit a broad range of adult consumers.

BACKGROUND OF THE INVENTION

As BMI increases, both the Hip Circumference measurement and WaistCircumference measurement increase. However the Waist Circumferenceincreases at a higher rate than the Hip Circumference. This causes theWaist Circumference measurement to approach the Hip Circumferencemeasurement in higher BMI women, whereas the Hip Circumferencemeasurement is typically larger than the Waist Circumference measurementin lower BMI women. The Hip Circumference measurement, due to therelationship to the prominent point of the buttocks, generallyestablishes the primary anchoring point of the absorbent article as itoften represents the maximum circumference around the body. This isespecially true for women who have a more cylindrical body shape or amore apple-like body shape. In alternative embodiments the WaistCircumference measurement can be the primary anchoring point of theabsorbent article as it can represent the minimum circumference aroundthe body especially for women who have a more hourglass body shape or amore pear-like body shape. This is a function of fit at the minimumcircumference, which means the product circumference and as a resultforce at the waist would have to increase to slide or sag due to theincreased body dimension at the hip. For products comprising one uniformelastic material or a series of uniformly strained strands of material,the hip may be the highest force region in the waist-encircling portionof the article, especially for hour glass or pear shaped body styles.For higher BMI women and women of different shapes, the high forceregion can extend toward the waist as the Waist Circumferencemeasurement approaches the Hip Circumference measurement, for example inwomen having a cylindrical or apple shape. The Hip Circumference andWaist Circumference are illustrated in FIG. 1. The relationship of theHip Circumference to the Waist Circumference (Hip Circumference-to-WaistCircumference Ratio), as illustrated in FIG. 2, is an important productdesign parameter to ensure that the shape of the product in the waistregion more closely approximates the shape of the female body in thewaist region. Having an understanding of the relationship between theHip Circumference and Waist Circumference enables targeting of elasticforces based on the body shape to enable improved fit, comfort andgasketing. Elastic forces that are too high as well as elastic forcesthat are too low can both have a negative impact on fit, performance andcomfort. High force leads to fit that is too tight and uncomfortable dueto skin marking and low forces lead to loose fit, sagging and potentialleakage due to poor gasketing.

The Hip Width and Waist Width are illustrated in FIG. 3. The BodyHip-to-Waist Silhouette, as illustrated in FIGS. 4 and 5 correlates withthe Hip Circumference-to-Waist Circumference Ratio as the values of bothdecrease as BMI and Waist Circumference increase. This is shown in FIGS.2, 4, and 5.

As the Hip Circumference increases with BMI and Waist Circumference, HipCircumference-to-Waist Circumference Ratio and Body Hip-to-WaistSilhouette both decrease. A key benefit of having the ProductHip-to-Waist Silhouette closer to that of the Body Hip-to-WaistSilhouette and designed to change accordingly with BMI and WaistCircumference is that the product itself more closely matches the shapeof the body. This results in the product being deformed to asignificantly lesser degree during application than one that isgenerically designed to generically fit a bigger range as illustrated bythe current marketed products. It also results in a product fit, whichis more tailored to the body shape, providing more effective gasketingand more targeted force and pressure distribution between the hip andwaist. In fact, many of the current marketed products are designed tofit increments as large as 100 pounds and, as such do not provideadequate fit, gasketing, comfort and discretion across the entire range.Additionally, product designs, which mimic the general shape of the bodyconvey to consumers a better, more tailored fit as the ProductHip-to-Waist Silhouettes are more similar to consumers' BodyHip-to-Waist Silhouettes. The designs enabled by the present disclosureare more targeted by design and therefore provide a greater level offit, gasketing, comfort and discretion.

Adult incontinence (“AI”) absorbent articles of the present disclosuremay be used to absorb and contain liquid and other discharges from thehuman body to prevent the body and clothing from becoming soiled. Foradults who suffer from urinary incontinence, urine voiding consists oftwo general types: stress urinary incontinence (“SUI”) and urge urinaryincontinence (“UUI”). SUI is caused by high pressure on the bladderinduced by coughing, sneezing, laughing, bending, etc., and can resultin a high flow rate though at a smaller urine volume that is associatedwith UUI. UUI can result in a full bladder release, though at a lowerflow rate than that associated with SUI.

Adult Incontinence articles come in a variety of designs, each typicallyavailable in multiple sizes, including 2, 3 and 4 size arrays. The sizeof articles of the prior art typically affects, for example, the size ofthe waist opening, the size of the openings around the thighs, and thelength or “pitch” of the article. Many of these prior art articles aredesigned to fit ranges up to 100 pounds. The prior art articles aretypically sized and sold by waist circumference dimension. The varioussizes can have a range in waist circumference of as much as 12 inchesand in some cases up to 16 inches. If a consumer selects an adultincontinence article of the prior art which is size appropriate based onthe waist circumference dimension of the wearer given the large rangesassociated with the various sizes, the thigh openings or pitch of thearticle, for instance, may be too large for proper fit on the wearer,potentially leading to slipping, sliding, sagging, drooping, or a lossof gasketing effects that are designed to inhibit leakage.Alternatively, depending on where the wearer is within the large sizerange, the thigh opening or pitch of the article may be too small forproper fit, potentially leading to wearer discomfort, skin marking ofthe wearer's skin or improper application or positioning of the articleon the wearer.

Desirably, an adult absorbent article should be designed and sized tomaintain contact with and conform as closely as possible to a wearer'sbody. Such a body-conforming design may increase the effectiveness ofthe adult absorbent article by reducing the possibility that urine, orthe like, will spread or travel along the wearer's body and leak out ofrather than be absorbed into the adult absorbent article. However,current adult absorbent articles on the market do not adequately addressbody shape or product shape and therefore do not fit a broad range ofusers adequately or provide the desired level of close fit. Typically AIpackages of adult absorbent articles are labeled with a recommendedwearer waist circumference range that the packaged article is intendedto fit. As a result, the waist circumference is often the sole criteriaused to identify the size of an AI article. The waist size does not initself adequately describe the body shape of the individual andtherefore does not help define the hip or thigh circumference nor thepitch that may be needed to provide the proper fit, comfort, coverageand gasketing of the article. This is the case even though othercharacteristics and anthropometric attributes of potential wearers (forexample, age, height, weight, thigh circumference, and rise) may varywidely within the recommended waist circumference range, and may resultin an ill-fitting article even though a wearer's waist circumferencefalls within that range. There is a need for adult absorbent articlesthat conform well to various wearers' body shapes and sizes. While thereis a wide range of body shapes and sizes among women, available productsdo not reflect this wide range; rather, absorbent articles availabletoday within a given product array tend to be scaled versions of eachother, and do not even follow the natural trend of body shape anddimensional changes across the range of consumers, i.e. smaller tolarger women as well as women of varying shape.

Body Mass Index (BMI) is on the rise globally for both men and women. Inthe U.S. alone, more than ⅓ of adult females are now considered obese(BMI>30). This has changed significantly over the past 30 years; in 1980only about 16% of U.S. adult females were obese. Larger women exhibitdifferent ratios of body anthropometrics than smaller women, i.e., allbody dimensions do not simply scale-up as women get larger. In addition,women across the range of BMI may also have very different body shapes.There is a lack of recognition and understanding of this issue bycurrent adult absorbent article manufacturers and as such consumers'needs are not being adequately met. Therefore, there is a need todevelop adult absorbent articles for a wide variety of body shapes andsizes in order to provide an improved level of fit and contact betweenthe body and the adult absorbent article to reduce the occurrenceleakage and improve the overall fit, comfort, coverage and discretion ofthe article. There is a clear need for adult absorbent articles whichare designed for variety of wearers based on their BMI and body shape.There is also a need to communicate to wearers the benefits of suchcustomized adult absorbent articles in an easy-to-understand manner(e.g., some women may not understand what BMI is or know their BMInumber), which is not off-putting (e.g., without stigmatizing orembarrassing women based on their BMI).

These are all objects of the present disclosure; embodiments of thepresent disclosure may combine various objects mentioned. A particularembodiment may, but need not, embody every object as described.

DETAILED DESCRIPTION OF THE INVENTION

“Pull-on garment” or “pant” means articles of wear which have a definedwaist opening and a pair of leg openings and which are pulled onto thebody of the wearer by inserting the legs into the leg openings andpulling the article up over the waist.

“Disposable” means garments, which are not intended to be laundered orotherwise restored or reused as a garment (i.e., they are intended to bediscarded after a single use and to be recycled, composted or otherwisedisposed of in an environmentally compatible manner). The pull-ongarment may be “absorbent” such that it absorbs and contains the variousexudates discharged from the body.

“Closed form” means opposing waist regions are joined to form acontinuous waist opening and leg openings. See FIGS. 15-17.

“Array” means a display of packages comprising disposable articles ofdifferent sizes having like article constructions (e.g., sameelastomeric materials [compositionally and/or structurally] in theflaps, graphic elements) said packages having the same brand and/orsub-brand, and said packages oriented in proximity to each other in agiven area of a retail store. An array is marketed as a line-up ofproducts normally having like packaging elements (e.g., packagingmaterial type, film, paper, dominant color, design theme, etc.) thatconvey to consumers that the different individual packages are part of alarger line-up. Arrays often have the same brand, for example, “Depend,”and same sub-brand, for example, “for Women Underwear.” A differentarray may have the brand “Depend” and the sub-brand “Silhouette ForWomen.” The differences between the “for Women Underwear” array and the“Silhouette For Women” arrays include different elastomeric materials inthe side flaps, where “for Women Underwear” comprises strands as theelastomeric material and “Silhouette For Women” comprises a filmelastomeric material.” Furthermore, the packaging is distinctlydifferent in that “for Women Underwear” is packaged in a predominatelygreen, film bag and “Silhouette For Women” is packaged in apredominately maroon box.

Further regarding “Arrays,” as another example of two separate “arrays”having the same brand, “Certainty,” one line-up has the sub-brand“Women's Underwear.” A different array may have the same brand“Certainty” and the sub-brand “Smooth Shape Briefs for Women.” Thedifferences between the “Women's Underwear” array and the “Smooth ShapeBriefs for Women” arrays include different elastomeric materials in theside flaps, where “Women's Underwear” comprises strands as theelastomeric material and “Smooth Shape Briefs for Women” comprises afilm elastomeric material.” Furthermore, the packaging is distinctlydifferent in that “Women's Underwear” is packaged in a predominatelyblue, film bag and “Smooth Shape Briefs for Women” is packaged in apredominately maroon box.

Arrays also often have the same trademarks, including trademarks of thebrand, sub-brand, and/or features and/or benefits across the line-up.

“On-line Array” means an “Array” distributed by a common on-line source.

“Hip Circumference” means the circumference of the body at the level ofthe maximum posterior protuberance of buttocks. See FIG. 1.

“Hip Width” means the horizontal distance at the front of the body atthe hips, where the hips are defined at the same level as the maximumprominent point of the buttocks as seen from the side. See FIG. 3.

“Waist Circumference” means the horizontal circumference of the waist atthe level of the center of the navel (omphalion). See FIG. 1.

“Waist Width” is defined as the width of the body measured horizontallyin the front of the body at the omphalion (center of navel). See FIG. 3.

“Hip Circumference-to-Waist Circumference Ratio” means the HipCircumference (mm) divided by the Waist Circumference (mm). See FIG. 1.

“Body Hip-to-Waist Silhouette” means the Hip Circumference (mm) dividedby the Waist Circumference (mm). See FIG. 3.

“Product Hip-to-Waist Silhouette” means Relaxed Product Hip Width (301)(mm) divided by the Relaxed Product Waist Width (302) (mm). See FIG. 6.

“Array Average Product Hip-to-Waist Silhouette” means the averageProduct Hip-to-Waist Silhouette of each size offered in a product array.For example, the Depend Underwear for Women (Maximum Absorbency) ismarketed and sold in an array of 3 sizes: Small/Medium; Large and ExtraLarge. The Array Average Product Hip-to-Waist Silhouette is the averageof: The Product Hip-to-Waist Silhouette for size Small/Medium; theProduct Hip-to-Waist Silhouette for size Large; and the ProductHip-to-Waist Silhouette for size Extra Large. Table 1 shows examples ofthe Product Hip-to-Waist Silhouette for some currently marketed productarrays.

“Relaxed Product Length” means the longitudinal distance between thelongitudinally distal most point in the crotch region and thelongitudinally distal most point along the front waist edge. Thelongitudinal distance is measured parallel to the longitudinal axis ofthe product. Refer to FIG. 6.

“Relaxed Product Hip Width” means the lateral distance from thelaterally distal most point of the left side edge of the product at theupper edge of the left leg opening to the laterally distal most point ofthe right side edge of the product at the upper edge of the right legopening. Refer to FIG. 6. The lateral distance is measured perpendicularto the longitudinal axis of the product.

“Relaxed Product Waist Width” means the lateral distance from the distalmost point at the right side of the front waist edge to the distal mostpoint at the left side of the front waist edge. The lateral distance ismeasured perpendicular to the longitudinal axis of the product. Refer toFIG. 6.

“Relaxed Product Side Length” means the linear distance from the pointof intersection between the waist edge and the side edge of the productto the point of intersection between the top of the leg opening and thesame side edge of the product. The relaxed product side lengthmeasurement is the average of the measurements from the left and rightsides of the product. Refer to FIG. 6.

“Target Waist Range” means the waist range as defined on each productpackage. For example, the Depend for Women Moderate Absorbency S/Mpackage indicates a waist of 28-40 in (71-102 cm).

“Average Targeted Waist” means the average of the Target Waist Range.For example, the Depend for Women Moderate Absorbency S/M has a TargetWaist Range (as defined on its package) of 71-102 cm. The AverageTargeted Waist for this product is 86.5 cm.

Consumers who are urinary incontinent often are traumatized by thecondition. Many aspects of the condition contribute to the trauma, likethe fear of having an incontinent event in public. Even when wearing anabsorbent article, there is still the fear of leaking, and the fear ofher absorbent article being noticeable under her clothes. As suchproviding a product experience that helps normalize the condition byproviding a more underwear-like, thin and body conforming structureacross the entire BMI range is one of the objects of the presentdisclosure.

The body mass index (BMI) is a classification system for body shapesbased upon height and mass. BMI may be calculated as follows:

${B\; M\; I} = {\frac{{weight}\; ({kg})}{{height}\; (m)^{2}} = \frac{703*{weight}\; ({lb})}{{height}\; ({in})^{2}}}$

The BMI comprises different classes of body mass, including: underweight(BMI<20), normal weight (BMI 20-25), overweight (BMI 25-30), obese (BMI30-40), and morbidly obese (BMI>40).

FIG. 7 illustrates how the general female body shape changes as BMIincreases. FIG. 8 illustrates a variety of specific shapes that mayexist within each BMI class: rectangle (also known as cylindrical),hourglass, pear, and apple. The higher her BMI, the further to the right(toward the apple) a women typically is on this body shape scale. Theprevalence of these shapes differs among BMI ranges, for instance,higher BMI women have a higher probability of being apple or pearshaped. Adult absorbent articles may be marketed to women of aparticular body shape, such as apple, rather than focusing on exact BMIvalues (which may be off-putting to a consumer), in order to match awearer with the article that will best fit her unique body shape orsize.

One region where the shape of the female body changes as BMI gets higheris in the Body Hip-to-Waist Silhouette. The Body Hip-to-Waist Silhouettegets smaller on average for larger women. FIGS. 4 and 5 illustrate howthe Body Hip-to-Waist Silhouette changes as both BMI and WaistCircumference gets larger.

It may be desirable to link the Product Hip-to-Waist Silhouette to thatof the targeted consumers Body Hip-to-Waist Silhouette in order toachieve a better fitting, better conforming, better gasketing product.This may increase the wearing comfort for each consumer while reducingleakage. Additionally, a product array where the Product Hip-to-WaistSilhouette of each subsequently larger size follows the same generaltrend as the Body Hip-to-Waist Silhouette for each subsequently largersize may also deliver a better fitting, better conforming article toeach consumer regardless of their respective BMI.

While today's AI product arrays are not targeted toward the consumer'sBMI, they are targeted toward their Waist Circumference. Table 1 detailssome of today's marketed product arrays (“comparative example arrays” or“existing product arrays”). FIG. 9 shows how the Product Hip-to-WaistSilhouettes of these arrays compare to the consumers' Body Hip-to-WaistSilhouettes. It can be seen that for these comparative example arrays ofthree or more sizes, their Product Hip-to-Waist Silhouettes not onlyfail to match those of their target consumers, but it can also be seenthat the trend from size to size for the existing product arrays is thatthe Product Hip-to-Waist Silhouettes get larger rather than smaller asdo the Body Hip-to-Waist Silhouettes of the consumers. The result ofthis mismatch is that the products provide an inferior level of fit,comfort, coverage and gasketing across much of the BMI range thanproducts that are designed in line with the anthropometric measuresacross the same BMI range.

Both of the side edges 137 may extend longitudinally between thefront waist end edge 136 and the back waist end edge 138. The chassis100 may form a portion of the laterally extending front waist end edge136 in the front waist region 36 and a portion of the longitudinallyopposing and laterally extending back waist end edge 138 in the backwaist region 38. Furthermore, the chassis 100 may comprise an interiorsurface 102, an exterior surface 104, a longitudinal axis 42, and alateral axis 44. The longitudinal axis 42 may extend through a midpointof the front waist end edge 136 and through a midpoint of the back waistend edge 138, while the lateral axis 44 may extend through a midpoint ofthe first side edge 137 a and through a midpoint of the second side edge137 b.

In various embodiments, a portion of or the whole absorbent article 10may be made to be laterally extensible. The extensibility of theabsorbent article 10 may be desirable in order to allow the absorbentarticle 10 to conform to a body of a wearer during movement by thewearer. The extensibility may also be desirable, for example, in orderto allow the caregiver to extend the front waist region 36, the backwaist region 38, the crotch region 37, and/or the chassis 100 to provideadditional body coverage for wearers of differing size, i.e., to tailorthe absorbent article 10 to the individual wearer. Such extension mayprovide the absorbent article 10 with a generally hourglass shape, solong as the crotch region 37 is extended to a relatively lesser degreethan the waist regions 36 and/or 38. This extension may also impart atailored appearance to the absorbent article 10 during use.

Any or all portions of the absorbent article may comprise abacteriophage composition as described in U.S. Ser. No. 61/931,229,titled DISPOSABLE ABSORBENT ARTICLES COMPRISING BACTERIOPHAGES ANDRELATED METHODS, and filed on Jan. 24, 2014.

Topsheet

In one embodiment, referring to FIGS. 12 and 19, the absorbent article10 may comprise a topsheet 81. The topsheet 81 may be compliant, softfeeling, and non-irritating to the wearer's skin and may be elasticallystretchable in one or more directions. Further, the topsheet 81 may beliquid pervious, permitting liquids (e.g., menses, urine, and/or runnyfeces) to penetrate through its thickness. Various topsheets may alsocomprise a hydrophilic material, for example, which is configured todraw bodily fluids into an absorbent core of the chassis 100 when thesefluids are expelled from the body. A suitable topsheet 81 may bemanufactured from a wide range of materials, such as woven and nonwovenmaterials, apertured or hydroformed thermoplastic films, aperturednonwovens, porous foams, reticulated foams, reticulated thermoplasticfilms, and/or thermoplastic scrims, for example. Suitable aperturedfilms may comprise those described in U.S. Pat. Nos. 3,929,135,4,324,246, 4,342,314, 4,463,045, 5,006,394, 5,628,097, 5,916,661,6,545,197, and 6,107,539.

Apertured film or nonwoven topsheets typically may be pervious to bodilyexudates, yet non-absorbent, and have a reduced tendency to allow fluidsto pass back through and rewet the wearer's skin. Suitable woven andnonwoven materials may comprise natural fibers, such as, for example,wood or cotton fibers, synthetic fibers, such as, for example,polyester, polypropylene, or polyethylene fibers, or combinationsthereof. If the topsheet 81 comprises fibers, the fibers may bespunbond, carded, wet-laid, meltblown, hydroentangled, or otherwiseprocessed, for example, as is generally known in the art.

The topsheet may comprise a skin care lotion. Examples of suitablelotions include, but are not limited to, those described in U.S. Pat.Nos. 5,607,760; 5,609,587; 5,635,191; 5,643,588; and 5,968,025, and asdescribed in U.S. Application No. 61/391,353.

In one embodiment, the topsheet may comprise graphics (e.g., 116 in FIG.15) such that depth perception is created as described in U.S. Pat. No.7,163,528.

Backsheet

In one embodiment, referring to FIGS. 18 and 19, for example, theabsorbent article 10 may comprise a backsheet 83. The backsheet 83 maybe impervious, or at least partially impervious, to fluids or bodyexudates (e.g., menses, urine, and/or runny feces) and may bemanufactured from a thin plastic film, although other flexible liquidimpervious materials may also be used. The backsheet 83 may prevent thebody exudates or fluids absorbed and contained in an absorbent core ofthe absorbent article 10 from wetting articles which contact theabsorbent article 10, such as bedsheets, pajamas, clothes, and/orundergarments. The backsheet 83 may comprise a woven or nonwovenmaterial, polymeric films such as thermoplastic films of polyethylene orpolypropylene, and/or a multi-layer or composite materials comprising afilm and a nonwoven material (e.g., having an inner film layer and anouter nonwoven layer). A suitable backsheet may comprise a polyethylenefilm having a thickness of from about 0.012 mm (0.5 mils) to about 0.051mm (2.0 mils). Examples of polyethylene films are manufactured by ClopayCorporation of Cincinnati, Ohio, under the designation BR-120 andBR-121, and by Tredegar Film Products of Terre Haute, Ind., under thedesignation XP-39385.

One suitable material for the backsheet can be a liquid imperviousthermoplastic film having a thickness of from about 0.012 mm (0.50 mil)to about 0.051 mm (2.0 mils), for example including polyethylene orpolypropylene. Typically, the backsheet can have a basis weight of fromabout 5 g/m² to about 35 g/m². The backsheet can be typically positionedadjacent the outer-facing surface of the absorbent core and can bejoined thereto. For example, the backsheet may be secured to theabsorbent core by a uniform continuous layer of adhesive, a patternedlayer of adhesive, or an array of separate lines, spirals, or spots ofadhesive. Illustrative, but non-limiting adhesives, include adhesivesmanufactured by H. B. Fuller Company of St. Paul, Minn., U.S.A., andmarketed as HL-1358J. An example of a suitable attachment deviceincluding an open pattern network of filaments of adhesive is disclosedin U.S. Pat. No. 4,573,986. Another suitable attachment device includingseveral lines of adhesive filaments swirled into a spiral pattern isillustrated by the apparatus and methods shown in U.S. Pat. Nos.3,911,173; 4,785,996; and 4,842,666. Alternatively, the attachmentdevice may include heat bonds, pressure bonds, ultrasonic bonds, dynamicmechanical bonds, or any other suitable attachment device orcombinations of these attachment devices.

In one embodiment, the backsheet 83 may be embossed and/ormatte-finished to provide a more cloth-like appearance. Further, thebacksheet 83 may permit vapors to escape from the absorbent core of theabsorbent article 10 (i.e., the backsheet 83 is breathable) while stillpreventing, or at least inhibiting, fluids or body exudates from passingthrough the backsheet 83. In one embodiment, the size of the backsheet83 may be dictated by the size of the absorbent article 10 and thedesign or configuration of the absorbent article 10 to be formed, forexample.

Absorbent Core

In various embodiments, referring to FIGS. 18 and 19, the absorbentarticle 10 may comprise an absorbent core (also referred to as an“absorbent member” or “absorbent assembly” or “absorbent structure” or“absorbent composite”) 200 that is disposed between the topsheet 81 andthe backsheet 83. The absorbent core 200 may comprise a laterallyextending front edge 236 in the front waist region 36, a longitudinallyopposing and laterally extending back edge 238 in the back waist region38, a first longitudinally extending side edge 237 a, and a laterallyopposing and second longitudinally extending side edge 237 b. Both ofthe side edges 237 may extend longitudinally between the front edge 236and the back edge 238. In one embodiment, more than one absorbent core200 or more than one absorbent core layer may be provided in anabsorbent article 10, for example. The absorbent core 200 may be anysuitable size or shape that is compatible with the absorbent article 10.Example absorbent structures for use as the absorbent core 200 of thepresent disclosure that have achieved acceptance and commercial successare described in U.S. Pat. Nos. 4,610,678; 4,673,402; 4,888,231; and4,834,735.

In one embodiment, suitable absorbent cores may comprise cellulosicairfelt material. For instance, such absorbent cores may comprise lessthan about 40%, 30%, 20%, 10%, 5%, or even 1% of the cellulosic airfeltmaterial as determined by weight. Additionally, such an absorbent coremay be primarily comprised of an absorbent gelling material in amountsof at least about 60%, 70%, 80%, 85%, 90%, 95%, or even about 100% asdetermined by weight. Furthermore, a portion of the absorbent core maycomprise a microfiber glue (if applicable). Such absorbent cores,microfiber glues, and absorbent gelling materials are described in U.S.Pat. Nos. 5,599,335; 5,562,646; 5,669,894; 6,790,798; and 7,521,587 andin U.S. Pat. Publ. No. 2004/0158212.

In one embodiment, the core, including multiple layers making up thecore system, may be printed and embossed as described in U.S. Pat. No.8,536,401.

In one embodiment, the core may be separable from the chassis asdisclosed in U.S. Pat. Nos. 6,989,006; 7,381,202; 7,175,613; 7,824,386;7,766,887; and 6,989,005. In such embodiments, the measurementsdescribed in this disclosure may be made to the chassis alone or may bemade to the chassis in combination with the separable core/absorbentassembly.

In one embodiment, the absorbent article of the present disclosure, andparticularly, a portion where the absorbent member is disposed, may havea body fluid absorption rate greater than 3 g/sec according to U.S. Pat.No. 6,649,810. According to U.S. Pat. No. 6,649,810, the expression “theportion (of the absorbent article) where the absorbent member isdisposed” is intended to mean the portion occupied by the absorbentmember when the absorbent article is flatly unfolded and seen in itsplan view.

In one embodiment, the absorbent structure may have an intake factorgreater than 3 according to U.S. Pat. No. 7,073,373, wherein the intakefactor is defined as the absorbent core permeability divided by thenormalized retention capacity (which is defined by the RetentionCapacity Test—also according to U.S. Pat. No. 7,073,373).

In one embodiment, the absorbent composite has a body fluid absorptiongreater than 75 g/100 cm², according to U.S. Pat. No. 6,649,810.

In one embodiment, a target location of the absorbent article may have awicking value greater than 36%, according to U.S. Pat. No. 6,383,960.

In one embodiment, the absorbent article may have a bending stiffnessbetween 0.05-1.0 gf, according to U.S. Pat. No. 5,810,796.

In one embodiment, the absorbent article may have a crotch fluidabsorption rate greater than 3 g/sec according to U.S. Pat. No.6,649,810. In one embodiment, a freeze-dried composite of the absorbentcomposite may have an intake rate of at least about 1.9 cubiccentimeters (cc) of liquid/second at 80% composite saturation accordingto U.S. Pat. No. 6,689,934.

Leg Cuffs

In one embodiment, referring to FIGS. 13 and 14, the chassis 100 of theabsorbent article 10 may comprise longitudinally extending and laterallyopposing leg cuffs 147 a and 147 b that are disposed on the interiorsurface of the chassis 100 that faces inwardly toward the wearer andcontacts the wearer. The leg cuffs 147 a and 147 b may comprise one ormore elastic gathering members disposed at or adjacent the proximal edgeof one or both of the leg cuffs 147. In addition, the elastic gatheringmembers of the leg cuff may also comprise one or more elastic strands146 disposed at or adjacent the distal edge of one or both of the legcuffs 147. The elasticized leg cuffs 147 may comprise severalembodiments for reducing the leakage of body exudates or fluids in theleg regions. The elasticized leg cuffs 147 are sometimes referred to asleg bands, barrier cuffs, elastic cuffs, or gasketing cuffs. Suitableelasticized leg cuffs 147 may comprise those described in U.S. Pat. Nos.3,860,003, 4,909,803, 4,695,278, 4,795,454, 4,704,115, and 4,909,803,and U.S. Pat. Publ. No. 2009/0312730. The leg cuffs 147 may be formed byfolding portions of the chassis 100 laterally inward, i.e., toward thelongitudinal axis 42, to form both the respective leg cuffs 147 and theside edges 137 a and b of the chassis 100. In other embodiments, the legcuffs 147 may be formed by attaching an additional layer or layers tothe chassis 100 at or adjacent to each of the respective side edges 137a and 137 b of the chassis 100. In one embodiment, the chassis 100 mayalso comprise other elastics disposed adjacent the side edges 137 whichmay cause the article 10 to form into a “U” shape when allowed to relaxthereby pulling the interior surface 102 of the front waist region 36toward the interior surface 102 of the back waist region 38.

In one embodiment, each leg cuff 147 may comprise a proximal edge 157 aand 157 b. These edges 157 a and 157 b are positioned proximate to thelongitudinal axis 42 compared to distal edges 139 a and 139 b. The legcuffs 147 may overlap the absorbent core 200, i.e., the proximal edges157 a and 157 b lie laterally inward of the respective side edges 237 aand 237 b of the absorbent core 200. Such an overlapped configurationmay be desirable in order to impart a more finished appearance to theabsorbent article 10 than that imparted by a non-overlappedconfiguration. In other embodiments, the leg cuffs 147 may not overlapthe absorbent core 200.

In one embodiment, each leg cuff 147 may be attached to the interiorsurface 102 of the chassis 100 in a leg cuff attachment zone (not shown)adjacent to the front waist end edge 136 and in a longitudinallyopposing leg cuff attachment zone (not shown) adjacent to the back waistend edge 138. In one embodiment, between the leg cuff attachment zones,the proximal edge 157 of the leg cuff 147 remains free, i.e., notattached to the interior surface 102 of the chassis 100 or to theabsorbent core 200. Also, between the longitudinally opposing leg cuffattachment zones, each leg cuff 147 may comprise one or more(specifically including one, two, three, or four elastic strands per legcuff 147) longitudinally extensible cuff elastic gathering members 159that may be disposed at or adjacent to the proximal edge 157 of the legcuff 147 by any suitable methods. Each of such cuff elastic gatheringmembers 159 may be attached over the leg cuff's entire length or overonly a portion of the leg cuff's length. For example, such cuff elasticgathering members 159 may be attached only at or near the leg cuff'slongitudinally opposing ends and may be unattached at the middle of theleg cuff's length. Such cuff elastic gathering members 159 may bedisposed in the crotch region 37 and may extend into one or both of thefront waist region 36 and the back waist region 38. For example, anelastic gathering member 159 may be attached at or adjacent to theproximal edge 157 of each of the leg cuffs 147 and extends into both thefront waist region 36 and the back waist region 38.

In various embodiments, each cuff elastic gathering member 159 may beenclosed inside a folded hem for example. In various embodiments, thecuff elastic gathering members 159 may be sandwiched between two layersforming the leg cuff 147, by two layers of the chassis 100, or may beattached on a surface of the chassis 100 or the leg cuff 147 and remainexposed.

In one embodiment, when stretched, the cuff elastic gathering member 159disposed adjacent to each leg cuff's proximal edge 157 allows the legcuff proximal edge 157 to extend to the flat uncontracted length of thechassis 100, e.g., the length of the chassis 100. When allowed to relax,the cuff elastic gathering member 159 contracts to pull the front waistregion 36 and the back waist region 38 toward each other and, thereby,bend the article 10 into a “U” shape in which the interior of the “U”shape may be formed by the portions of the article 10 that are intendedto be placed toward the body of the wearer (i.e., interior surface 102).Because each of the proximal edges 157 remains free between thelongitudinally oriented leg cuff attachment zones, the contractive forceof the elastic gathering member 159 may lift the proximal edge 157 ofthe leg cuff 147 away from the interior surface 102 of the chassis 100.This lifting of the proximal edges 157 when the article 10 is in therelaxed condition lifts the leg cuffs 147 into a position to serve asside barriers to prevent, or at least inhibit, leakage of bodilyexudates.

Waistband

In one embodiment, referring to FIG. 14, the article 10 may comprise anelasticized waistband 112 a and b. The elasticized waistband may provideimproved fit and containment and may be configured to elastically expandand contract laterally to dynamically fit a wearer's waist. Theelasticized waistband may extend longitudinally outwardly from the waistedge of the absorbent article 10 toward the waist edge of the absorbentcore 200. In one embodiment, the absorbent article 10 may have twoelasticized waistbands, one positioned in the back waist region 38 andone positioned in the front waist region 36, although other pantembodiments may be constructed with a single elasticized waistband. Theelasticized waistband may be constructed in a number of differentconfigurations including those described in U.S. Pat. Nos. 4,515,595 and5,151,092.

In one embodiment, the elasticized waistbands may comprise materialsthat have been “prestrained” or “mechanically prestrained” (i.e.,subjected to some degree of localized pattern mechanical stretching topermanently elongate the material). The materials may be prestrainedusing suitable deep embossing techniques. In other embodiments, thematerials may be prestrained by directing the material through anincremental mechanical stretching system as described in U.S. Pat. No.5,330,458. The materials may then be allowed to return to theirsubstantially untensioned condition, thus forming a zero strain stretchmaterial that is extensible, at least up to the point of initialstretching. Examples of zero strain materials are disclosed in U.S. Pat.Nos. 2,075,189, 3,025,199, 4,107,364, 4,209,563, 4,834,741, and5,151,092.

Flaps

The flaps 189 (a-d) may be discrete from or integral with the chassis100. A discrete flap is formed as separate element, which is joined tothe chassis 100. In some embodiments, this includes a plurality offlaps, e.g. 2 or 4 (often referred to as ear panels or side flaps) beingjoined to the side edges 137 a and b of the chassis in the front and/orrear waist regions 36 and 38 (see FIGS. 12-17). In other embodimentsthis may include a front and/or back belt-like flaps (“belts”) beingjoined across the front and back (or rear) waist regions of the chassis100, at least across end edges of the chassis 136 and 138 (see FIGS. 12and 19). In some embodiments the waistbands 112 can overlap the flaps tocreate a continuous belt-like structure (see FIG. 14).

The belt-like flaps and may comprise an inner nonwoven layer and anouter nonwoven layer and elastics there between. The inner and outernonwoven layers may be joined using adhesive or thermoplastic bonds.Various suitable belt-like flap configurations can be found in U.S. Pub.No. 2013-0211363.

An integral flap is a portion, one or more layers, of the chassis thatprojects laterally outward from the longitudinal edge. The integral flapmay be formed by cutting the chassis to include the shape of the flapprojection.

While many of the embodiments illustrated in this application havingbelt-like flaps are pant articles, taped articles may have belt-likeflaps disposed in one or both waist regions as well.

The structure of flaps play an important role in the functionality ofthe absorbent article and are fundamentally different than the elasticsused in underwear. As mentioned above, incontinence events, such as SUIand UUI, can result in a high flow rate and/or a full bladder release.The amounts of urine expelled during the incontinence events can varywildly given the type of urinary incontinence as well as othercircumstances such as time since last bathroom visit, amount of fluidintake, day or night, etc. Loadings can range from as low as a few dropsof urine to loadings as high as 600 mls. It is not unusual to havesingle loadings as high as 300, 400 and even 500 mls. These levels ofloading present a significant downward force associated with the loadingwhich can be a pound or more. This downward force must be compensatedfor by the absorbent article chassis in order to minimize sagging,gapping and leakage. In order to sustain the fit of the article evenafter loading the article comprises elastomeric element(s) 146,including films and/or strands) that are disposed proximate to and alongthe side seams 280 a and b (see, for example, FIG. 15, where theelastomeric elements 146 terminate proximate to and along the length ofthe seams 280 a and b) of the article and extend laterally from one sidetoward the other. These elastomeric element(s) should create a normalforce against the body sufficient to anchor the article. The location ofthe elastomeric element(s), as well as the forces exerted by theelastomeric element(s) can be varied to ensure proper anchoring at thehips and along the body specifically across the front waist region andin the back waist region. One form of anchoring beneficial forsustaining the fit of a loaded article is disclosed in U.S. Pat. No.5,358,500 Absorbent Articles Providing Sustained Dynamic Fit issued Oct.25, 1994 to LaVon, et al. It should also be noted that regular underwearwith elastic along the waist edge and leg edges would not typicallyprovide sufficient support to sustain the fit of the underwear if aweight of 300-600 grams was applied to the crotch region of theunderwear.

Fastening System

The absorbent article may also include a fastening system. Whenfastened, the fastening system interconnects the front waist region 36and the rear waist region 38 resulting in a waist circumference that mayencircle the wearer during wear of the absorbent article 10. This may beaccomplished by flaps 189 a and b in the back waist regioninterconnecting with flaps 189 c and d in the front waist region or byflaps in the back waist region interconnecting with the chassis 100 inthe front waist region. The fastening system may comprises a fastener 53a and b such as tape tabs, hook and loop fastening components,interlocking fasteners such as tabs & slots, buckles, buttons, snaps,and/or hermaphroditic fastening components, although any other knownfastening means are generally acceptable. The fasteners may releasablyengage with a landing zone 118, which may be a woven or nonwoven. Someexemplary surface fastening systems are disclosed in U.S. Pat. Nos.3,848,594; 4,662,875; 4,846,815; 4,894,060; 4,946,527; 5,151,092; and5,221,274. An exemplary interlocking fastening system is disclosed inU.S. Pat. No. 6,432,098. The fastening system may also provide a meansfor holding the article in a disposal configuration as disclosed in U.S.Pat. No. 4,963,140. The fastening system may also include primary andsecondary fastening systems, as disclosed in U.S. Pat. No. 4,699,622.The fastening system may be constructed to reduce shifting of overlappedportions or to improve fit as disclosed in U.S. Pat. Nos. 5,242,436;5,499,978; 5,507,736; and 5,591,152.

Identical or Substantially Identical Chassis

As disclosed in U.S. Pub. No. 2013-0211355, it may be desirable to offeran array of packages for fitting different sized wearers, but comprisingidentical or substantially identical chassis. For instance, an array maycomprise a first package comprising a first size of absorbent articlesand a second package may comprise a second size of absorbent articles,where the first and second packages comprise identical or substantiallyidentical chassis as described in U.S. Pub. No. 2013-0211355. Moreparticularly, the first package may comprise a first chassis and thesecond package may comprise a second chassis, where each of the firstand second chassis comprise the same dimensions of one or more of: corewidth at the lateral centerline, core width at one of the front or rearcore end, a distance from a left outer cuff distal edge to a right outercuff distal edge, a distance from a left inner cuff distal edge to aleft outer cuff distal edge, a distance from a left inner cuff proximaledge to a right inner cuff proximal edge, a distance from a left innercuff proximal edge to a left outer cuff distal edge, a free height ofthe inner cuff, inner cuff hem fold width, inner cuff elastics length,outer cuff elastics length, core length, and backsheet width.

Further, each of the first and second chassis may comprise identicalchemical compositions of one or more of a topsheet, backsheet film,backsheet nonwoven, core super absorbent polymers, core pulp, corenonwoven, core tissue, leg cuff film, leg cuff nonwoven, super absorbentpolymer adhesive, core nonwoven adhesive, leg cuff elastic adhesive, andbacksheet nonwoven/film adhesive.

And, each of the first and second chassis may comprise the same basisweight of one or more of the topsheet, backsheet film, backsheetnonwoven, core super absorbent polymers, core pulp, leg cuff nonwoven,leg cuff film, super absorbent polymer adhesive, leg cuff adhesive, andbacksheet nonwoven/film adhesive.

And, each of the first and second chassis may comprise compositionallyidentical core super absorbent polymers. The first and second chassismay have identical component cross sectional order and disposition in atleast one of the front waist region, back waist region, and crotchregion. The inner leg cuffs of the first and second chassis may becomposed of the compositionally identical materials.

And, the core adhesives of the first and second chassis may be the sameadhesive(s). The first and second chassis may comprise core superabsorbent polymers that are in the same chemical class and subclass.

And, each of the first and second chassis may comprise first and secondwetness indicators, respectively, and wherein the first and secondwetness indicators are compositionally identical.

Further, the inner leg cuffs of the first and second chassis may haveidentical component cross sectional order and disposition in at leastone of the front waist region, back waist region, and crotch region. Thedistance from the left outer cuff distal edge to a right outer cuffdistal edge may the same. The distance from the left inner cuff proximaledge to left outer cuff distal edge may be the same. The distance fromthe left inner cuff proximal edge to the right inner cuff proximal edgeis the same. The lengths of the inner and outer cuffs are the same.

In some embodiments, different size offerings in an array may haveidentical or substantially identical chassis as the flaps or belts maybe used to enable the absorbent article to fit different sized wearers.For example, first and second absorbent articles may have identicalchassis (compositionally, dimensionally, cross-sectionally), but thefirst article may have a different length due to disposition of thebelts, such that the first article may be targeted to fit a smallerwearer than the second article. As a second example, first and secondabsorbent articles may have identical chassis (compositionally,dimensionally, cross-sectionally), but the first article may have adifferent length and/or width due to the size of the belts, such thatthe first article may be targeted to fit a smaller wearer than thesecond article.

In some embodiments, first and second absorbent articles may haveidentical chassis compositionally, but not dimensionally, and notcross-sectionally. In some embodiments, first and second absorbentarticles may have identical chassis dimensionally, but notcompositionally, and not cross-sectionally. In some embodiments, firstand second absorbent articles may have identical chassiscross-sectionally, but not dimensionally, and not compositionally. Instill other embodiments, first and second absorbent articles may havetwo, but not three of (1) compositionally, (2) dimensionally, and (3)cross-sectionally identical chassis.

Test Methods

Product Measurement Preparation

All measurements are conducted at 22° C.+/−2° and 50% RH+/−20%.

Purpose

This method is used to prepare pant type products for subsequentdimensional measurement. The method provides a consistent means ofopening a product that has been removed from a bag. This method isapplicable to all forms of pant products. A constant rate of extensiontensile testing machine with computer interface is used.

A load cell is chosen so that the load cell capacity ensures accuracy ofa 5N load to within 0.1N.

Sample Holder Apparatus

“C” (304) and “O” (305) Bar attachments each with a rod radius of 9.50mm that extend longer than the length of the longest side seam. Refer toFIG. 20. The bars are mounted horizontally in the tensile tester withtheir longitudinal axes in the same vertical plane and with upper barmounted directly above the lower bar.

Equipment Set Up

Calibrate tensile tester equipment according to the instrumentmanufacturer's recommendations. The initial gauge length is determinedby removing 10 sample products from the bag, unfolding the pant products(307) and laying them flat as illustrated in FIG. 21, below andmeasuring the distance between the sides of the pant at the waist asshown (306). The average of the waist measurement will be used as theinitial gauge length for the specific set of specimens. The initialgauge length is the distance from the uppermost edge of the upper bar tothe lowermost edge of the lower bar.

Apply the whole product (307) to the bars as shown in FIG. 22 whileminimizing manipulation of the specimen.

Pull Sample to 5N Force then hold for 10 seconds. Return to initialgauge length.

Crosshead Speed=254.0 mm/min, Data acquisition rate=50 Hz.
